2 Claims. (Cl. .5- -262) This invention relates to spring bed bottoms, Fig. -'7 is a plan view of the structure illustrated bed springs or the like and more particularly in Fig. 6. to means for stabilizing the movement of a top Referring to the drawings, the spring bed botframe of a bed spring with reference to a bottom comprises an upper frame iii preferably comtom frame which, through interposed springs,- posed of angle metal, a lower frame I! which support the top frame. An important object may also be formed of angle metal, and coil comof the present invention is to provide novel and pression springs l2 interposed in a suitable manadvantageous stabilizing means of the general ner between end bars iii of the upper frame it character specified. and end ones of the cross bars 84 of the lower 0 One important feature of the present invenframe H as shown in Fig. 1 to assist in the sup- 1 tion involves the use at a desired position along port of the upper frame from the lower. The a bed spring of a cross member which is spring end bars of the lower frame H are suggested by supported from the bottom frame, and spring the broken horizontal line at the left of Fig. 1, stabilizing devices interposed between the cross extending from that frame. Further support member and the upper frame, the spring stabilizof the upper frame II] from the lower frame is ing devices supported by the cross member beobtained by additional coil springs i2 which are ing desirably weaker than the spring supports Within the two frames and are supported by adfor the cross member whereby for light stresses ditional cross-bars, such as l4, (Fig. 2), connect the spring stabilizing devices substantially alone ing the opposite side rails of the lower frame. are adapted to give, although also there may be Such use of coil springs, as l2, throughout a bed A comparatively a very slight give to the spring bottom or similar structure and supported on supports for the cross-member, but these will cross bars I4 is well known in the art and reyield to a greater extent under greater stresses quires no further illustration. imposed on the spring stabilizing devices, with Stabilization of the upper frame ill with refthe result that any up or down movement of such erence tothe lower frame I! may be effected by cross-member is minimized and is not as great use f n or m r stabilizing assemblages, w as the up or down movement of the top frame. being illustrated in F ACCOTdiHg e p These being among the objects, feature nd ferred embodiment of the invention illustrated in advantages of the present invention, the same Figs- 1 and 2, each Stabilizing assemblage 0 mconsists of certain features of construction and prises a Cross member 15 ec ed at e h e d 39 combination of parts to be'hereinafter described to '7 Side f 10W?! frame it y means o a ea y and then claimed with reference to the accom- 116110941 tension SDYmg and Stabilizing means panying drawings illustratingapreferred embodidevices supported on and above the f of merit of the invention and modifications of certhe cross member and connected Wlth the w feature and wherein corresponding sides of the top frame in. 35

The tension springs 20 preferably are weak- Fig. 6 is a fragmentary View illustrating in eleer than the springs it. As indicated on Fig. 1 vation a third form of spring support for the the lower ends of the arms I! constitute stops cross member of the stabilizing means; and that engage the upper edges of cross member I5 55 and limit upward movement of the top frame Hi.

There should be stabilizing means at opposite sides of the two frames I0, ll, so that if a person should sit on one side of the bed and thus depress the top frame H], the stabilizing means at that.

side will act to restore the top frame to its predetermined upper position when such persons weight is removed. Upon thus depressing a side rail of the top frame the latter is tilted, with the result that the flat under surface of such depressed rail, to which the arm I! preferably is" of the arm I1 is moved away from the cross member l5 even if the arm is rigid as preferred, and, as the said rail moves down substantially vertically, the inner en-d'of the arm is moved away from the corresponding rail of the frame H, At the same time, but after first partly depressing resiliently mounted member Hi, the arm I! fulcrums on the upper pivot of longer link I8 and pushes back thereon, thus swinging back shorter link l9, and, inasmuch as the extreme inner end of the arm is now pushed in, in spaced relation to the cross member IS, the upper pivot of such link I9 has put the spring 20 under the tension imposed by the weight of the person sitting on the corresponding side of the bed. As such person rises from sitting position the tension of the spring 20 and of springs I 6 promptly restores the elements of the stabilizer to the normal position shown in Fig. 1, and brings the frame l back to its original position, any further upward movement thereofbeing stopped by the extreme inner end of the arm I I, or the lower corner thereof at that end, coming in contact with the cross member I5. The slight vertical movement of the cross member i relatively to the greater degree of depression of frame I11, and which cross member movement is afforded by the springs I6, is also of advantage as it means that the further down the depressed side rail of the frame 50 goes after first somewhat depressing resilient cross member [5, the greater is the spacing between the extreme inner end of arm I! and the cross member l5, the springs l6 and 20 acting together to restore the arm I! and the. top frame to their normal positions in which the extreme inner end of the arm is brought into abutting relation with the cross member 15.

It will be evident that the stabilizing means hereinbefore described will be very effective in maintaining the proper relation between the top frame I0 and the bottom frame ll.

Referring to the modification shown in Figs. 4 and 5, the only substantial change from the stabilizing means Of Figs. 1, 2 and 3 resides in the use, at each end of a slightly modified cro'ss member Rid, of two tension springs lBa attached at their inner ends to the cross member I 5a and diverging toward the adjacent side of the lower frame II to which they are secured. In the specific form shown the member I5a is twisted so as to provide a horizontal portion at its ends which portion is provided at opposite sides of its middle line with perforations through which the ends of the springs lBa pass. Preferably the other ends of these springs are connected with the ends of cross bars 14 of the lower frame II. This arrangement tends of course to resist turning of the cross member I 5a, thus holding the stabilizer such as IT in an upright plane.

Referring to the modification illustrated in Figs. 6 and 7, it will be seen that it differs from that of Figs. 4 and 5 only in arranging springs l6b, diverging from the end of cross member l5b, in a vertical plane and in securing their outer ends to a vertical member 2| attached to the adjacent side of the lower frame II.

In all forms of the invention the spring structure is adapted to be compressed into a narrow space as compared with the depth of the structure when the same is in using position, which permits a smaller package to be made for shipping or storage.

It should be understood that changes may be made in the construction and arrangement and that certain features may be used without others without departing from the true scope and spirit of the invention.

WhatI claim as new is- 1. In a bed spring or the like, the combination of a top frame and a bottom frame, springs supported from the bottom frame and acting on and supporting the top frame, a cross-member extending between opposite sides of the bottom frame and positioned between the lower ends of the supporting springs, the extremities of the cross-member terminating at points spaced inwardly from such opposite bottom frame sides, tension springs connecting such'extremities of the cross-member with such opposite sides, and stabilizing means above and supported on each end of the cross-member and between the tension springs and each such means including arms inclined downwardly and inwardly from the top frame and attached to opposite sides thereof, a pair of links of different lengths piv oted to the lower end of each arm and pivotally connecting the links with the corresponding end of the thus tensioned cross-member, the longer link being further out on the cross-member than the shorter link, and the links converging toward the arm, together with a tension spring connecting the upper pivot of the shorter link with the lower pivot of the longer link.

2-. In a bed spring or the like, the combination of a top frame and a bottom frame, springs supported from the bottom frame and acting on and supporting the top frame, a cross-member extending between opposite sides of the bottom frame and positioned between the lower ends of the supporting springs, the extremities of the cross-member terminating at points spaced inwardly from such opposite bottom frame sides, helical tension springs connecting such extremities of the cross-member with such opposite sides, and stabilizing means above and supported on each end of the cross-member and including arms inclined downwardly and inwardly from the top frame and attached to opposite sides thereof, a pair of links of different lengths pivoted to the lower end of each arm and pivotally connecting the links with the corresponding end of the crossmemberfthe longer link being further out on the cross-member than the shorter link, and the links converging toward the arm, together with a tension spring connecting the upper pivot of the shorter link with the lower pivot of the longer link, the lower ends of the arms constituting stops, located inwardly of the shorter links, striking the cross member and limiting upward movement of the top frame.
